In a few places, we fill a GEM object with data, or overwrite some

evicted due to memory pressure.
The cases where only a single page is touched are dealt with in a
separate patch.
This incorporates and supercedes Alex Dai's earlier patch

Hm, did you drop the begin_cpu_access dma-buf one here? See my other mail,
I think that one was legit.

I did, because I didn't know whether it was necessary and Chris was
dubious. But I can easily reinstate it in the next (v3) series.
